 Product Description

The CMBE Booster is designed for domestic and commercial water supply, pressure boosting, irrigation and dewatering applications.

The CMBE series is available in both 1x110-120V and 1x200-240V variants and uses energy efficient, permanent magnet motor technology, which provides unmatched reliability, quiet operation, and energy savings.

Thanks to the integrated speed controller, the CMBE keeps a constant pressure in the pipe system. A pressure sensor monitoring discharge pressure will signal to the speed controller to change the motor speed to adapt the performance to the new situation.


  • Constant pressure via integrated speed control
  • Compact design
  • Robust, stainless steel design
  • Easy installation
  • Low energy consumption
  • Dry-running protection
  • Noise level below 55 dBA and even lower at controlled speed

The CMBE Booster is a complete pump system preassembled with the following components:

  • CME pump with integrated frequency converter
  • 5-way fitting with non-return valve
  • Diaphragm tank
  • Pressure gauge
  • Pressure sensor

The simple control panel features the GRUNDFOS Eye that indicates system status, warnings and alarms. Adjusting to the desired setpoint is easy using the one-touch control buttons. The light fields on the control panel will indicate the setpoint setting.
